Application filed May 5, 1919. Serial No. 294,770.

To all whom it may concern Be it known that 1, JAMES C. DAWSON, a citizen of the United States, and resident of lVebster Groves, county of St. Louis, and State of Missouri, have invented certain new and useful Improvements inBookbinding, of which the following is a specifica tion, and which are illustrated in the accompanying drawings, forming a part thereof. v

The invention relates to the art of book binding and has for its object the provision of an inexpensive but permanent binding, including both covers and back, for loose sheets which may be conveniently used when the preservation of a quantityof such sheets is required but only occasional reference to the sheets is anticipated.

To this end the invention contemplates a construction in which the sheets are secured,

between separate covers after which the back is formed to protect the ends of the sheets at the hack of the volume.

Further features of theinvention will be described in connection with'the construction shown in the accompanying drawings, in which Figure 1 is a perspective view showing a bound volume made in accordance with the invention;

F ig. 2 is a perspective view showing a pound volume prior to the formation of the ack' Fig. 3 is a view similarto Fig. 2 show ing another form of fastening;

Fig. 4 is a view similar to Fig. 2 showing still another form of fastening; and

Fig. 5 is a detail sectional view throng one of the back forming flaps,

In carrying out the invention a quantity of the sheets to be preserved are collected together to fornia stack 10. Covers, as 11 and 12, are then applied to the stack 10 upon opposite sides of the same. The covers 11 and 12 are preferably of like construc tion and each cover is desirably formed from inexpensive soft materials as a layer of binders board inclosed in canvas. To facilitate the future examination of the sheets the binders board is preferably omitted in each cover 11, 12, upon a line adjacent to and parallel with one end of the cover, thereby forming a hinge 13.

The covers may be secured to the sides of the stack 10 in a variety of ways, three suitable methods being illustrated in Figs. 2, 3

and 4c. In the method shown in Fig. 2 sharp nails 14 are forced into the stack 10 from opposite sides, hrough the. corresponding cover. It the nails, as shown, are of such length as to pass completely through the stack and the opposite cover the projecting ends le should preferably be out ofi, after insertion, flush with the outer surface of the cover on the far side instead of clenching. There are no openings for receiving the nails 14: either in the covers 11, 12, or in the sheets forming the stack prior to the entry of the nails. The nails are frictionally held throughout their length with sufficient force to prevent the subsequent separation of thesheets by any ordinary method of handling the completed volume. r

In the method shown in Fig. 3 the covers and the shee s forming the stack are punched and through these apertures a Wire 15 of U-shape is inserted and its ends sub: sequently turned over or clenched as at 15. Metallic plates .16 and 17 are preferably provided for distributing and equalizing the pressure of the wire on the covers. In the method shown in Fig. 4 the covers and the sheets forming the stack are punched and through these apertures cords or tapes are passed, the ends of which are drawn taut and knotted at 19. a To form a back for the bound volume flaps 20 are provided oneach cover. These flaps are attached by adhesive, sewing or other means to the faces of the covers along one edge thereof, preferably with one edge registering with an edge of the cover and the opposite. edge normally extending toward the opposite edge of the cover. The fastening devices, whether nails, wire, cords or tape, arearranged to pass through that part of each flap 20 which is secured to the cover so that when the flap is folded rearwardly to form the back, as shown in Fig. 1, the fastening devices are entirely concealed. As the flaps are preferably formed of stiff material they are scored along the lines where they are folded rearwardly and where r they are folded over the edges of the covers to facilitate bending.

As the stacks to be bound will vary in height the flaps 20 are preferably made long enough to pass across the back of the highest stack likely to be bound and reach the edge of the opposite cover. For smaller sized stacks the flaps are cut to the desired length and to facilitate cutting them evenly lines 21 maybe printed and scored'or simply scored on the inner face of the flaps. After cutting to the requisite length one flap is secured to the back of the stack by adhesive which may be conveniently applied to each flap at the time the covers are manufactured.

The flap on the opposite cover is 'then on those edges of the flaps which extend are preferstrip 22 as Fig. 5.

between the covers, these edges ably bound over With a fabric illustrated more particularly in I claim as my invention:

1. The method of binding loose sheetsvto form a permanent record volume which consists'in assembling the sheets in a stack,.applying a flexible cover andflap to each side of the stack, forcing a plurality of sharp nails into the stack from opposite sides oi the samenear one edge through the corresponding covers and flaps without previous perforation of the sheets or covers inline with thenails and without clenching the nails, folding said flaps each upon itself so as to cover the nails and about the back of the volume and gumming one flap to the back edges of the sheets in the stack-and the other flap to the first named flap.

2. In abook, in combination, a stack of.

sheets, a pair of covers applied-to opposite sides of the stack of sheets, i'astening devices for securing one edge of eachof the covers tothe stack, and a back forming flap se cured to one cover adyacent said edge, w th V its free endnormally extending toward the opposite edge ot the same coverbut adapted to be folded back and to. be secured by adhesiveto the back edges of the sheets in the stack; I v j i r 3.111 a book,in combination, a stack of sheets, a pair of covers applied to opposite sides of the stack of sheets, fastening devices for securing one edge of each of vthe covers to. the stack, and a back forming fiap secured to one cover adjacent saidedge, with its free end initially extending toward the the flap when the latter is in back-forming 7 position:

In a book, in combination, a stack of sheets, a pair of covers applied to opposite sides of the stack of sheets, fastening devices for securlng one edge of each ot the covers to the stack, and back forming flaps secured to the covers adjacent said edges wlth their free ends initially extending toward the opposite edge 01 the cover to which the are attached and folded back and secured by adhesive to the back edges of the sheets in the stack and to the opposite fiap respectively, the ends of the fastening devices being between the cover and the backwardly folded portions of the flaps ivh en the latter are in'hack forming tion.

' 5. In a book, in combination, a stack oi? sheets, a pair of covers applied to opposite sides of the stack of sheets, a back-forming flap secured to the back edge of one of said covers with its free end initially extending toward the opposite edge of the same cover, fastening devices for securing one edge of each of the covers and of the flap to the stack, the initially tree portion, of the flap folded upon, the secured portion and secured by adhesive to the back edges of the sheets in thestack and to the secured end of the opposite cover.
